Specification of Letters Patent. I

Patented Oct. 12,1915.

Application filed February 2, 1915. Serial No. 5,784.

To all whom it may concern:

Be it known that I, JOSHUA H. GRIFFITH, a citizen of the United Statesof America, residing at Ellis, in the county of Ellis and State ofKansas, have invented certain new and useful Improvements inGas-Generating Burners, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to gas generating burners and has for itsprincipal object the production of a burner which may be placed withinthe fire box of a stove in such a manner as to allow the burner toeasily heat the desired portions of the stove when the same is inoperation.

Another object of this invention is the production of a gas generatingburner which is so formed as to easily vaporize the oil so that upon themixing of the vaporized oil with the air, a gas will be produced whichis adapted to be ignited upon passing from the interior of the burner.

Another object of this invention is the production of a gas generatingburner having a simple and efficient means for regula'tingthe amount ofvaporized oil which is adapted to be admitted to the mixing cham berwhereby the amount of gas produced may be increased or diminished asdesired.

A still further object of this invention is the production of a gasgenerating burner having a plurality of burner pipes extending from itsgas chamber whereby the burner pipes may extend to desired positionswithin a stove so that the various portions of the stove may be heatedas desired.

WVith these and other objects in vi'ew,'this invention consists ofcertain novel combinations, constructions, and'arrangements of parts aswillbe hereinafter fully, described and claimed.

In the accompanying drawings :Figure 1 is a detailed perspective view ofthe gas generating burner. Fig. 2 is a central longitudinal sectionthrough the burner. Fig. 3 is a top plan view of the device. Fig. 4 is ahorizontal longitudinal section through the device, taken below thecentral partition.

Fig. 5 is an end elevationof the burner.

Fig. 6 is a section taken on the line 6-6 of Fig. 2. Fig. 7 is a sectiontaken on the line 77 of Fig. 2. Fig. 8 is a fragmentary sectional viewof a portion of the device illustrating the manner in which the valvemember is carried. Fig. 9 is a'detailed perspective view of the valvestem. Fig. 10 is a fragmentary detailed perspective view of theupperportion of the burner, showing the gas pipes extending therefrom.

Referring to the accompanying drawings by numerals it will be seen that-1 indicates the body of the burner which is preferably cylindrical inshape but which may be so constructed as to embody any desired shape orformation. This body 1 comprises a casing which is hollow and has oneend thereof closed by the head 2 andthe opposite end thereof closed bythe head 3. The head 3 is provided with a plurality of openings 4thereby forming the stays 4. It will be seen that by providing theopenings 4, air maybe admitted into the interior of the casing 1 as theoccasion requires. A partition 5 is fixedly secured within the interiorof the casing 1 adjacent its central portion so as to extend in ahorizontal plane as will be seen by referring to Fig. 2. This partition5 has an integral wall 6 formed upon one end thereof, which wall 6extends at right angles to the partition 5 so as to be connected totheinncr upper portions of the casing 1 thereby forming a tight closureat one end of the partition 5. The opposite end of' this partition 5however terminates at'aspaceddistance from the end 2 as indicated at 3in Fig. 2 for the purpose of allowing the gas formed in the mixingchamber to pass around this end of the partition. A number of apertures7 are formed in the casing 1 for the purpose of allowing the gas carriedwithin the gaschamber 8 to escape from the interior of the burner and tobe easily ignited as the samepas'ses through the apertures 7. A pipe 9is carried upon the upper portions of the casing 1 so as to extendaround the apertures 7 as clearly shown in Figs. 1 and '3. This pipe 9is fixedly retained in position upon the casing by means of the clips 10which embrace the pipes and are fixedly secured upon'theupper portionsof the casing in any suitable manner It will. be seen that as the oilpasses through the pipe 9 the heat from the flames caused by the burningof the gas passing through the apertures 7' will heatthe pipes and causethe oil to be vaporized before it reaches the mixing chamber. Thispipe'9 is provided with an elongated depending neck 13 whichcommunicates with the valve casing 14 by means of the neck 14. vThisneck 13 extends upwardly to communicate with the valve casing 1 1 withinthe air chamber 11. The valve-casing 14: extends entirely through theair chamber 11 and co1nmunicates with the interior of the mixing chamber12. In order to retain this valve casing in its correct position one endthereof is carried by the thickened portion of the head 3 while thecentral standard 15 is adapted to be positioned upon the valve casingfor the purpose of supporting the inner end thereof. This standard 16extends in a vertical position so as to bear against the vertical wall 6or the partition 5. The valve member 21 is provided with a grippingportion 22 which may be easily gripped so as to actuate the valve member21 as the occasion requires. a; threaded portion 23 is formed. upon thevalve member 21 and this threaded portion 23 is adapted to pass throughthe threaded opening 21 formed in the thickened. portion 15 of the head3; It will be seen that the valve member 21 extends tliroughout theentire length of the casing 143 so as to pass from the inner portions ofthecasing as clearly shown in Fig. 2. Since the casing 1i tapers towardits inner end the inner end of the valve member 21 will become wedged asshown at 21 in Fig. 2 for the purpose of cutting off the supply of?vaporized oil when it is so de sired.

When the device is in operation air will pass through the openings 1formed in the iead 3 and into the air chamber 11. The air may then passdownwardly into the miX- ing chamber 12 under the partition 5. Thegripping portion 22 may then be actuated so asto'movethe valve member 21and allow oil to pass into the mixing chamber 12. As the oil and airmix. a. gas will be formed which will pass around the end of thepartition 5 and will pass into the gas chamber 8; As the gas passes fromthe chamber 8 through the a ertures? it may ignite so asto' allow theflames to heat any desiredarticle or receptacle or to heat a stovewithinwhich the burner is positioned. As the flames heat the pipe 9 the oiltherein will be vaporized so that upon passing through the neck 13 intothe casinghl it may bedischarged in a vaporized condition from thecasing 14: into the mixing chamber thereby reducingthe cost of producingthe gas and causing the burner to operate more efficiently. It will ofcourse be seen that the draftof the air caused by the passage of the airinto the chamber 11 through the openings 4" will cause the gas formed inthe mixing chamber to quickly pass into the gas chamber 8" therebypreventing a backfire in the mixing chamber 12.

Itwill beseen thatthe'casing 1 isadapted to carry'a' nipple 25communicatingwith. the interior of the gas chamber 8'. The gas pipe 26maybe held in engagement with. the

nipple 25 by means of the collar 27. From this pipe 26, burner pipes 28may extend and the admission of gas to these pipes 28 may be regulatedby the valves 29. It will be seen that the gas from the chamber 8 will Ipass through the nipple 25 and into the pipe 26; As the various valves29 are actuated the gas will pass into the diiferent burner pipes 28 andwill be discharged through the burner openings 30. These openings may beprovided with a blaze deflector 31 supportedupon the frame 32 soias tocause the blaze-'inade by the igniting of the gas passing from theburner openings to be spread or deflected. It is obvious that the pipes26 and 28 may extend in any desired shape or to any desired position soas to efficiently heat the several portions of a stove Within which theburner is adapted to be positioned.

From the foregoing description it will be seen that a very efficient gasgenerating burner has been produced which is so formed as to be easilycarried within a stove for heating the stove and which has its severalparts so arranged as to readilyvaporize the oil before" the oil ispassed to the mixing chamber whereby a very pure gas may be veryquickly'and cheaply producedwhen the burner is in operation. It willalso be seen that the valve operating mechanism is so formed as toeasily control the supply of vaporized oil to themixing chamber,thisvalveoperating 'mechanismbeing easily supporglzed in aconvenient'po'sition to be operate It will be seen that" the casing 14':extends for a" considerable distanceinto the mixing chamberand'owing'tothe fact that the cool-' ing chamber is' formed adjacent oneend of this mixing chamber, the point Within the mixing chamber whereatthe vaporized oil is admitted is far-enough from the open end of thegenerating-burner to prevent the igniting of the vaporized oil by theflames without the burner. Therefore, it will be seen thatthe cloggingofthe'mixingchamber by the formation: of the-soot therein is preventedand consequently theburner will be clean within itsinner portions at alltimes so as to allow the gas to' be easily generated.

What I claim is 1. In a gas generatingburner of the class described, thecombination of a casing, a central partition carried within said casing,forminga'mi'xing chamber and agas chamber, said partition provided withan integral vertical wall extending at right angles thereto forming anair chamber, said partie tion terminating ata spaced distancesfrom oneend of'said casing to communicate said mixing and gas chambers, and'means for. supplying said mixing: chamber with vapors ized' oil, said"air chamber; having openings to the outside air and communicating withsaidinixing chamber whereby air'issupplied;

to the mixing chamber, said gas chamber having openings for the exit ofgas to be burned.
